The monitor of the Liquid crystal display or the LIQUID CRYSTAL MONITOR - the thin and flat device for display. It is made by a considerable quantity colour or monochromatic pikselov which are built by way of a light source or a reflector. It uses very small quantity of the electric power and therefore is used often in the electronic devices of the battery put in action. The used technology is very dissimilar with technology CRT which is used by many desktop monitors. It was used only on laptops during very long time. Only recently to them have offered as alternative to monitors CRT. They lift very much less table, do intervals and it is much easier than monitors CRT. But they also are rather expensive.
Everyone piksela display of the monitor of the LIQUID CRYSTAL MONITOR has a layer of the levelled molecules between two electrodes which are transparent also two filters of polarisation. As there is no liquid crystal between the levelled filters of polarisation, light which has passed through the first filter, will be blocked by the second polarizer. A surface which is in contact to a crystal, consider to level it in a specific management. The alignment management is defined by a rubbing management.
The decision, in terms of the horizontal and vertical size expressed in pikselah, native supported for the best effects of display. It is one of things which places the monitor of the LIQUID CRYSTAL MONITOR SEPARATELY. The size of a point is defined as distance between two adjacent pikselami. It is a minimum for sharper image. Everyone piksel is divided into three cells, or sub piksely. They are painted red, green and dark blue. Everyone sub pikselom can be operated independently for millions combinations and therefore paints. Senior monitors CRT use phosphors for sub structures piksela. An analogue electronic beam though amazes exact sub piksel.
Colour components can be built in various configurations, how the monitor should be used. If the used software knows geometry, it can be used to increase obvious number pikselov, using sub granting piksela. This kind of technics is often used in text smoothing. At LCDs which are used in a digital watch and calculators, there is a separate contact for each segment. Thus external specialised krugooborot charges each segment individually. It is not possible, if a number of elements increases.
Small one-colour displays as those used in Personal Organizers or in the senior laptops have a passive matrix as structure and use bent nematichesky or a double layer of the first-rate quality technology STN. Here, at each number or each column is unique electric krugooborot, and to pikselam hence address according to numbers and columns. But as the number of increases pikselov, umensheny any more does not remain to time of the answer and technics vypolnimym.
The colour displays used in modern monitors of the LIQUID CRYSTAL MONITOR and televisions, use structure of an active matrix. The set of transistors of a thin film (TFT) is added. Everyone piksela has a specialised transistor. The Zhk-screen with an active matrix looks brighter and sharper than passive matrix display of the similar size and has the best time of the answer.
The technology of the LIQUID CRYSTAL MONITOR has a few critical lacks also. Monitor CRT decision can be changed without introduction of any new exhibit. But LCDs can make only their native decision, and not native decisions are reached, measuring. Afro-Americans LCDs are actually grey because of light source presence. It leads to lower contrast relation when in comparison with CRTs. LCDs with cheaper parts cannot show so a lot of plasma of colours or copies CRT.
Besides, display of the LIQUID CRYSTAL MONITOR has longer time of the answer when in comparison with Plasma or copies CRT. The entrance delay also is present, and the consideration corner is limited. Despite these lacks, display of the LIQUID CRYSTAL MONITOR quickly receives outstanding position. |
